PULVERIZER.

To all 'whom t may camera Be it known that i.. Dinox S. CAn'rEn, a

1 citizen oi the llnite'd States, residing at lminimum of difficulty.

to provide means whereby the blade mayv be adjusted about the mold boardV at the will of dotted lines.

Bloomington, in the county ot lvlcLeaii and State oi illinois, have invented a certain new and useful improvement in ljulveriaers, oi which the following is a specification.

lily invention has'ior its object to prov i ier) new and improved means or fastening pnl verizerblades to a mold board. @ne object is to provide a unit assembly whereby a number oi'pulverizer. blades may be positioned about the outer edge of the mold board where they will Vdo their pulverizingl work with a maximum oi? eiiciency and Another object is the operator and to provide mea-ns whereby the blades` may be previously assembled as annit and then positioned on` the mold board without the possibility olf anyv change in position by them during operation. Another object iskto provide a light and vflexible and adjustable means for attaching` such pulverizer blades without interfering with the operation of the plower and without in-` terfering with the functioning ot the plow in any way. Y v

My invention is illustrated'more" or less' diagrammatically lin the accompanying drawing, whereinVV y Figure 'l shows a'perspective view oi' the mold board with other plow parts omitted.

Fig. 2 shows a side elevation oit the adjusting plate with cutting blades attached. the mold board position being `indicated in Fig. 3 shows a section along the line 3-3 of Fig. 2.

with a series of perorations. `B1 arranged in groups oit two at predetermined intervals.

it is tapered atits rear end as shownl at B2 I and provided with a series-ot perit'orations B3, arranged some et them concentrically about a'centi'al perforation B4, the distance between the different holes along aradial and riveted therethrough as shown in Figs. -2 and3. These knife handles areperforated Vas atCf, the perforations being arranged radially about` the central forward perf'orae tion C?, the distance between perforations on the radial line being substantiallyfthe same as: the distancebetween the pertoration groups B1 or between the pertorations Igrimpedabout Vthe central perforation'` Bft.

handle is bent up about the end lof the knife This handle@V3 is for themajor portion ,of i

the mold boarde while the handle is located entirely behind vthe mold board. so that the handle and all yhandle attaching andfcontrolling parts are passes acrossthe mold board.

klt will be noted that the handlesv their base plate and that they are bolted to the plate;` thehandle being bolted by two or `more bolts as the case mav be. TheV I bolts pass through theholes B1. B3 and hold Vthe knife handles on the plate. it being understood that theassemblv b v slight changes in relative position ot parts maybe adiusted -or right and lett hand plows, asvthecase mav' be. The bolt heads will nreterablv in either event be klocated between the plate yand alwavs located out of the line of movement ot the furrow sllce as 1tv10o selves are fiat as shown. t0 conform with the .i

the mold board and itvmake'slittle. if any dierenee on which eide oi' the plete the handles are located.

It will be evident theft Awhile I heye shown" in my drawings inoperative device, still many changes may be mede both in Size.

.Shape and arrangement of parte Without departing materially from the spirit of my invention, and l 'Wisin therefore, that my drewmgsv be regarded :is in e# sense dnigrammetio. 1

The use and operation of my invention are ee follows- The farmer or other user Wishing to an' *Yply my device to the mold board of his plow, takes the epernte knives with their handles and bolts them one et e. tune upon the brise plete changing their po, .on both -enguler and bodily with respect to the plate the knives assume the. position Shown in Fig. 1, arranging the parte such theteach slet and each knife Closely engages the edge of the mold board. Thisv can beV done plete is so positioned that the beltgwhieh passes thrfnigjfh` the mold boz'ird may pase through it sind then t iiough the brace. The itrner, after. the parte are in position tightens the bolts `andV nut, to clamp the parte together, and in this Situation the Vplete 'assiste 1n holding the plete and the knives rigidly end firmly in position. .here being' e certain amount oi iiexibility end elasticity to both the pleteendthe kniyee it isfobvions that there will be e slight ten- WithV n very` slight limit of adjustment, and thev vto clznnp or lock the knives liz'miy in position endet course Sincethe slots in the `rknives eleeely' engage the mold board, there is no tendency for the plete to be bent weyV from thevrmold board, and it will Conform more or lees closely to the curvature thereof. Thus the Whole knife eseembly may be etteched and detached as e unit to the mold board, and any individual knife may be atteohed and detached or any individuel knife or the Whole esgembly es e unit may be edjiieted with respect thereto.

l. The combination of a plowmold board with eer-ies ot' bledee slotted to engage its edge ind e common support for them, adepted to be edjiietebly'secured on the beek of and entirely within the edge the ymold board, each ble.` tion about the reel' edge of the board and :ze to its angle with refeience to the furrow strip end each' projecting upwardly into the path of the furrow strip end extending substantially inreer of the ree 'edge ofV the mold board. l
